Boost/Fuel Cut & Overboost Code
Posted: January 2nd, 2023, 5:48 am
Hello everyone.
I'm new to these forums so hopefully posting in the correct place. I've had an overboost and fuel/boost cut issue for the last while.
I am consistently getting fuel/boost cut with a P0234 overboost code. Every single time I go WOT, high in the rev range it will hit a wall. It feels jerky and not smooth either. Normal driving seems fine, it isn't until WOT that it breaks up. I have noticed that the "power" doesn't increase gradually with the throttle, it's like once I press the pedal around 70% It all comes at once and I can hear the turbo a lot louder.
I have rechecked all hose clamps multiple times and they are all definitely tight.
I'm currently running the OTS Versatune High Load Map, and the overboost seems to have started after that even before upgrading the intake. I'm really hoping that this issue is tune related, and a pro tune could fix this. I'm also wondering if the MAF housing is slightly larger than stock and it's messing with readings? Bearing in mind the weather is cold here too, was around 2°c during these logs.
Only mods I have currently is the Corksport Stage 2 TIP + Intake. I have triple checked all hose clamps.
Thanks in advance!
